(Cl. 167-22) The present invention relates to new ag kylation or aralkylation products, or the amcombating pests, consisting of salts of partially monium compounds thereof. Among these prodacylated polyamines as such, or in combination ucts those are particularly valuable which derive with other agents suitable for destroying pests. from high molecular acids. Among these there It comprises the said agents and their app may be mentioned palmitic acid, stearic acid, and 60 tion for the purpose disclosed. oleic acid, lauric acid, the naphthenic acids,

By the term pest ganic or organic acids with the partially acylated we understand, on the one hand, microorgamsln i polyamines. If desired polyamine salts of such 65 such as fungi, bacteria, prot z a, and the hk acids may be employed, which are themselves and, on the other hand, invertebrates, such as active against pests, such as for instance arsenites, biting Sucking insects, Worms, as for insta c arsenates, silicofluorides, benzoates, chlorobenzoearth worms, molluscs, such as snails, and so On. ates, salicylates, and so on,
